DAVID NEALE, OF ST. LOUIS, MISSOURI ART CF MAKING STAGGEHED DIKES.

SPECIFICATION forming part of Letters Patent No. 780,437, dated January17, 1905.

Application filed May 2, 1904.. Serial No. 205,851.

T0 aZZ whom it may concern:

Be it known that I, DAVID NEALE, a citizen of the United States, and aresident of St. Louis, Missouri,,have invented certain new and usefulImprovements in the Art of and Apparatus for Making Staggered Dikes. ofwhich the following is a specification containing a full, clear, andexact description, reference being bad to the accompanying drawings,forming a part hereof.

My invention relates to improvements in the method of and apparatus forconstructing dikes; and it consists of the novel features herein shown,described, and claimed.

- In the drawings, Figure 1 is a plan illustrating my-improved methodand showing the apparatus embodying the principles of my invention. Fig.2 is a perspective, upon an enljarged scale, of one of the anchors shownin Referring to the drawings in detail, the anchors comprise the boxes3, loaded with rock or other suitable weights. The anchor-ropes 5 aresecured to the anchors, and the anchors are sunk in suitable positionsin the bed 6 of the stream. The other ends of the ropes .5 are securedto stakes 7 driven in the bank 8,

so that the anchor-ropes extend into the stream at an angle of aboutforty five degrees, the stakes being above the anchors.

Obstructions 9, 10, and 11 are secured to obstruction-ropes 12, 13, or14:, said obstruction-ropes being slidingly attached to the anchor-ropes5 by eyes or loops, so that they will slide down the anchor-ropes towardthe anchors. The obstructions may be of any suitable construction, suchas rafts, bundles of brush, stumps of trees, or any other material whichwill catch the sediment of the stream, cause a deposit, andbuild up adike.

It will be convenient to use obstructions that will just float, so thatwhen they are turned loose the force of the current will draw them downinto the water as the obstructioncables slide down the anchor-cables.

This construction is suitable for use in any running stream where it isdesired to construct a dike to change the current to narrow into the bedof the stream; attaching cables to the anchors and to the bank at apoint above the anchors; and attaching obstructions to the cables, sothat'they will slide down the cables into the bed of the stream;specified.

substantially as 2. The improvement in the art of construct- I ingdikes, which comprises dropping anchors into the bed of the stream; andattaching obstructions so that they are held in position by the anchors;substantially as specified.

In testimony whereof I have signed my name to this specification inpresence of two subscribing witnesses.

DAVID N EALE.
